Title: Method and device for regulating the unevenness of a sliver
Inventor: MEILE HANSPETER
IPC: D01H5/42
Filed: 1981-03-14
Granted: 1984-05-10
Abstract: An autolevelling drawframe for levelling out staple fibre slivers in the spinning mill operation, in which deviations of the sliver weight (linear density) from the preset desired value detected are processed into correcting signals and are transmitted to a correcting member, which adapts the input speed of the drafting arrangement. The correcting signal transmitted is generated from the product of a voltage proportional to the rotational speed of the main motor and a voltage determined by the deviation in linear density. The apparatus consists of a computer (34,41; 60,41; 67,71) for computing the correcting signal, which computer is connected electrically with the correcting member (48), with a transducer (20) transmitting the voltage proportional to the rotational speed of the main motor, and with means for generating the voltage determined by the deviation in linear density. The computer can consist of a control device (36) and a multiplicator (41) or of a microprocessor (71) (digital computer).

Title: Tubular casing with an adhesive seam permeable to vapour, for foodstuffs, especially sausages, and process for its manufacture
Inventor: KLENK LUDWIG
IPC: A22C13/00
Filed: 1981-10-28
Granted: 1985-06-20
Abstract: Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm2 and an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. The adhesive layer is smoke-permeable and is preferably composed of a material system which sets without a chemical reaction. The film web is produced from viscose, and it is prevented from shrinking during the process and is stretched in the transverse direction during drying. The tubular casing finds particular application as a sausage casing.

Title: Salt bridge liquid for the potentiometric analysis of blood
Inventor: EISENHARDT ANNE ROSENGAARD
IPC: G01N27/28
Filed: 1983-05-17
Granted: 1987-10-15
Abstract: The salt bridge liquid contains Na<+>-ions and HCOO<->-ions in substantially equimolar amounts, preferably in a concentration larger than or equal to 1 M, in particular about 4M. 
<??>When this salt bridge liquid is used, the potentiometric measurement will give corresponding results when measuring a blood sample and the corresponding plasma sample because the suspension effect which is caused by the erythrocytes and which is seen when using other salt bridge liquids is substantially eliminated. Furthermore, different blood samples with the same ion concentration but with varying erythrocyte content will give corresponding measuring results.
